The Fitzpatrick skin phototype classification scheme has become the standard method for assessing the reaction of the skin to solar stimuli; this method can be easily biased by different factors, such as ethnicity or chronic sun exposure.
Diffuse reflectance spectrophotometry (DRS) is an objective and non-invasive method used in this work to determine constitutive skin color from the upper volar arm as an objective way of measuring skin pigmentation. A DRS-determined melanin index that accounts for skin pigmentation was obtained for 35 subjects of Hispanic origin, this melanin index was compared with the physician-diagnosed and self-reported skin phototypes.
The results show that at least for Hispanic individuals, there is a clear clinical distinction between subjects with skin phototype I and their DRS-determined melanin index; however, subjects with skin phototypes II-VI have a large melanin index overlap.
Clinical assessment of skin phototype can be complemented by using DRS.
菲茨帕特里克皮肤光型分类方案已成为评估皮肤对太阳刺激反应的标准方法；这种方法很容易受到种族或慢性阳光暴露等不同因素的影响。
漫反射光谱光度法（DRS）是一种客观的非侵入性方法，用于从上手背确定固有肤色，作为测量皮肤色素沉着的客观方法。对 35 名西班牙裔个体进行了基于 DRS 的黑色素指数测定，该黑色素指数与医生诊断和自我报告的皮肤光型进行了比较。
结果表明，至少对于西班牙裔个体，皮肤光型 I 的个体与 DRS 测定的黑色素指数之间存在明显的临床差异；然而，皮肤光型 II-VI 的个体具有较大的黑色素指数重叠。
可以通过使用 DRS 来补充皮肤光型的临床评估。
